Convert Python code to Matlab code

I need to convert following python codes to Matlab. Can anyone help me to convert following codes:

-The code is to access a folder path and change the name of every file inside: oldname.txt -> neg_oldname.txt.

import os

def rename_file(folder_path,change_str):
    for file in os.listdir(folder_path):
        old_file_path= os.path.join(folder_path,file) 
        if os.path.isfile(old_file_path):
            old_file_name=os.path.basename(old_file_path)
            new_file_name= change_str+old_file_name
            new_file_path=os.path.join(folder_path,new_file_name)
            
            os.rename(old_file_path,new_file_path)
folder_path =""
change_str=“neg_”

rename_file(folder_path,change_str)

If you tell the purpose of your code, people who dont use python can also help you to code it in MATLAB.

% create some files for testing
writematrix([3 4], 'test1.txt');
writematrix([5 6], 'test2.txt');
dir

.          ..         test1.txt  test2.txt  

folder_path = '';
change_str = 'neg_';
rename_file(folder_path,change_str)
dir

.              ..             neg_test1.txt  neg_test2.txt  

function rename_file(folder_path,change_str)
fn = dir(fullfile(folder_path, '*.*'));
for i=1:numel(fn)
    if ~ismember(fn(i).name, {'.', '..'})
        movefile(fullfile(folder_path, fn(i).name), fullfile(folder_path, [change_str fn(i).name]));
    end
end
end
